The paranasal sinuses, air-filled cavities within the skull, play a vital role in respiratory health and cranial structure, named after the bones they occupy. This image illustrates their locations, including the frontal sinus above the eyebrows, the maxillary sinuses below the orbits, the sphenoid sinus under the sella turcica, and the ethmoid air cells between the orbit and nasal cavity. This article explores the anatomical positioning, physical characteristics, and functional significance of these sinuses, offering a detailed guide for understanding their role in human anatomy.

The human nose represents an intricate masterpiece of anatomical design, featuring a complex network of nerves, blood vessels, bones, and soft tissues. This detailed cross-sectional diagram reveals the sophisticated internal anatomy of the nasal cavity, highlighting crucial structures that play vital roles in breathing, smell sensation, and overall respiratory health. Understanding these components is essential for medical professionals, students, and healthcare practitioners involved in treating nasal conditions.
